采用板的一阶剪切变形理论,对含有压电材料层的复合材料层合板,从机电耦合的变分方程及 Hamilton 原理出发,建立起求解其动态响应的有限元方程。同时也给出了压电材料层作为传感元件时的传感方程及作为作动元件时的作动方程。并采用速度反馈控制实现了层合板的主动振动控制。最后给出了计算实例。
Based on the first-order shear deformation theory of the plate, the finite element equation for solving the dynamic response of the composite material laminate with the piezoelectric material layer is established based on the electromechanical coupling variational equation and the Hamilton principle. At the same time, the sensing equation of the piezoelectric material layer as the sensing element and the operating equation of the piezoelectric element as the actuating element are also given. And the use of speed feedback control to achieve the active vibration control laminate. Finally, a calculation example is given.
